Water Purification and Reuse Project ExplainedDo you have questions about the City's Water Purification and Reuse project? Click the play button below to watch a short video which explains everything you want and need to know about the process.

Direct Potable Reuse Project (DPR)The DPR Project went online July 9, 2014 following extensive testing by the City of Wichita Falls and the Texas Commission on Environmental Quality (TCEQ). The installation of the project was completed in late December of 2013 followed by an intense 45-day testing protocol, as required by the TCEQ, to ensure that the water would be safe to drink. Following this testing the TCEQ requested an additional 30 days of tests. They then analyzed the results and met with City leaders and staff to discuss the findings. They approved a permit for the project on June 28, 2014. This innovative project provides 5 million gallons of water per day (1/3 of our daily demand). The project cost 13 million dollars.

The project has gone by several names but is now known as the DPR Project. Other well known titles:
•Emergency Reuse Project
•Short-Term Reuse Project
•Temporary Reuse Project

Engineering Professor Exams DPR Project Interest
University of Texas Engineering Professor, Desmond Lawler examines the growing interest in and safety of DPR projects. One of his quotes from the article, "If you want to drink very clean water, direct potable reuse will likely provide higher quality water than many drinking water plants currently produce now."

Steps in the DPR Water Treatment Process
1. Treated reuse water is disinfected and pumped to the Cypress Water Treatment Plant
2. The treated water is again treated through Microfiltration (MF)
3. The water is treated again through Reverse Osmosis (RO)
4. The MFRO treated reuse water is released into a holding lagoon
5. The treated reuse water is blended with lake water on a 50/50 basis
6. The blended water is treated through an eight step conventional treatment process
7. The water is stored and pumped to Distribution
